In my previous blog "PIC32MZ tutorial -- Output Compare", I shows how to apply Output Compare without interrupt to generate PWM signal. I also tried the Output Compare interrupt. I selected OC to be PWM mode without fault pin (OCM = "110&qu…
In my older blog "PIC32MZ tutorial -- Key Debounce", I shows how to acheive key debounce with port polling. At this moment, I write an application which uses External Interrupt. Therefore, only generates interrupt and starts debounce when the f…
Output Compare is a powerful feature of embedded world. The PIC32 Output Compare module compares the values stored in the OCxR and/or the OCxRS registers to the value in the selected timer. When a match occurs, the Output Compare module generates an…
The microcontroller is PIC32MZ2048ECH144 on the PIC32MZ EC Starter Kit. This microcontroller has four 32-bit synchronous timers are available by combining Timer2 with Timer3, Timer4 with Timer5, Timer6 with Timer7, and Timer8 with Timer9. The 32-bit…
Today I implement "Hello World" on PIC32MZ EC starter kit. The application of "Hello World" only lights up a LED. There are three LEDs on the starter kit board -- LED1 and LED2 and LED3. At the moment, I only light LED1 on RH0. Every…
Getting started: A skeleton application In order to build our application, we will start with theZendSkeletonApplication available on github. Use Composer to create a new project from scratch: $ composer create-project -s dev zendframework/skeleton-a…

Active Record (AR) 是一个流行的 对象-关系映射 (ORM) 技术. 每个 AR 类代表一个数据表(或视图),数据表(或视图)的列在 AR 类中体现为类的属性,一个 AR 实例则表示表中的一行. 常见的 CRUD 操作作为 AR 的方法实现.因此,我们可以以一种更加面向对象的方式访问数据. 例如,我们可以使用以下代码向 tbl_post 表中插入一个新行. yii 表单验证规则 <?php classContactFormextendsCFormModel { publ…

ROM Read-only memory (ROM) is a class of storage medium used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to distribute firmware(software that is very…
在做web开发中可能会遇到flash遮挡页面中元素的情况,无论怎么设置flash容器和层的深度(z-index)也无济于事,现有的解决方案是在插入flash的embed或object标签中加入”wmode”属性并设置为wmode=“transparent”或”opaque”,但wmode属性到底是什么意义,为什么可以解决这个问题呢? window mode(wmode) wmode即窗口模式总共有三种,看看当年Macromedia官方的说法: Window: Use the Window val…
